为什么ctags -R.不为子目录生成源代码索引？

Question

当前目录:

测试目录中有一些文件:

有很多文件在test目录中有main()函数:

[mirror@home libevent]$ find test/ -regex .*.c -exec grep main {} +
test/regress.c:struct testcase_t main_testcases[] = {
test/test-weof.c:main(int argc, char **argv)
test/regress_dns.c:/* FIXME: We should move this to regress_main.c if anything else needs it.*/
test/regress_buffer.c:  size_t remaining;
test/regress_buffer.c:  remaining = v[0].iov_len - 512;
test/regress_buffer.c:  tt_int_op(remaining, ==, v[0].iov_len);
test/regress_buffer.c:  remaining -= 8;
test/regress_buffer.c:  n = evbuffer_reserve_space(buf, remaining+64, v, 2);
test/regress_buffer.c:  tt_int_op(remaining, ==, v[0].iov_len);
test/regress_buffer.c:  remaining -= 1;
test/regress_buffer.c:  n = evbuffer_reserve_space(buf, remaining+64, v, 2);
test/regress_buffer.c:  tt_int_op(remaining, ==, v[0].iov_len);
test/regress_buffer.c:  /* Drain some of the remaining chunk, then add it to another buffer */
test/regress_main.c:    { "main/", main_testcases },
test/regress_main.c:main(int argc, const char **argv)
test/regress_main.c:    if (tinytest_main(argc,argv,testgroups))
test/tinytest.c:static int in_tinytest_main = 0; /**< true if we're in tinytest_main().*/
test/tinytest.c:        if (!in_tinytest_main) {
test/tinytest.c:                       " called from within tinytest_main.\n");
test/tinytest.c:tinytest_main(int c, const char **v, struct testgroup_t *groups)
test/tinytest.c:        ++in_tinytest_main;
test/tinytest.c:        --in_tinytest_main;
test/test-eof.c:main(int argc, char **argv)
test/test-ratelim.c:main(int argc, char **argv)
test/tinytest_demo.c:main(int c, const char **v)
test/tinytest_demo.c:   /* Finally, just call tinytest_main().  It lets you specify verbose
test/tinytest_demo.c:   return tinytest_main(c, v, groups);
test/test-time.c:main(int argc, char **argv)
test/bench_cascade.c:main(int argc, char **argv)
test/test-dumpevents.c:   remain in the future.
test/test-dumpevents.c:main(int argc, char **argv)
test/test-changelist.c:main(int argc, char **argv)
test/test-init.c:main(int argc, char **argv)
test/test-fdleak.c:main(int argc, char **argv)
test/bench_http.c:main(int argc, char **argv)
test/bench.c:main(int argc, char **argv)
test/bench_httpclient.c:main(int argc, char **argv)

但在我使用之后:

ctags -R .

然后打开vim

:tag main
:g ] 

状态栏只显示:

E433: No tags file
E426: tag not found: main

怎么了？标签文件已经加载,为什么没有标签文件？令人困惑......

似乎ctags生成的索引包含这些包含main函数的文件:

3643 main    sample/dns-example.c    /^main(int c, char **v) {$/;"   f
3644 main    sample/event-read-fifo.c        /^main(int argc, char **argv)$/;"       f

3649 main    sample/time-test.c      /^main(int argc, char **argv)$/;"       f
3650 main    test/bench.c    /^main(int argc, char **argv)$/;"       f
3651 main    test/bench_cascade.c    /^main(int argc, char **argv)$/;"       f

3660 main    test/test-ratelim.c     /^main(int argc, char **argv)$/;"       f

3662 main    test/test-weof.c        /^main(int argc, char **argv)$/;"       f
3663 main    test/tinytest_demo.c    /^main(int c, const char **v)$/;"       f
3664 main_callback   sample/dns-example.c    /^main_callback(int result, char type, int count, int ttl,$/;"  f       file:
3665 main_testcases  test/regress.c  /^struct testcase_t main_testcases[] = {$/;"    v       typeref:struct:testcase_t

但为什么标签main,g]找不到包含main函数的文件列表？

romainl的解决方案适用于:标记名称,即使启用了autochdir也是如此

我已经运行:set tags =./ tags,tags,即使当前dir被改为别人也可以工作,因为启用了autochdir,但g]有时可能不起作用,为什么？

但g]有时不起作用:

错误信息是E257:找不到cstag:tag

编辑2:.vimrc的内容

cat ~/.vimrc
set autoindent
colorscheme desert
set number

Answer 1

该E433错误意味着Vim没有找到您的tags文件,所以,不,标签文件尚未加载.

打字:set tags应输出如下内容:

./tags,tags

这是默认值,它的意思是"寻找一个tags位于当前文件的目录文件,然后在当前目录".

因为你有set autochdir,你可能会在没有tags文件的目录中结束.在test,例如.

要确保Vim找到您的tags文件,您应该使用以下内容:

set tags=./tags,tags;$HOME

这意味着"查找tags位于当前文件目录中的文件,然后在当前目录中,然后在任何父目录中查找$HOME".

好吧,上面的设置已经为我预期了很长一段时间.但这是我刚做的小实验(set autochdir当然有):

1. 我在~/workspace/accordion/那里只包含一个文件accordion.js.

2. 我这样做$ ctags -R .:~/workspace/accordion/tags创造了.

3. 我知道$ mkdir -p aa/bb/cc/dd/ee/ff.

4. 我知道$ vim aa/bb/cc/dd/ee/ff/test.js.

5. 在Vim中,我做:tag *mini这跳转到申报mini()方法,该成员Accordion()位于构造函数~/workspace/accordion/accordion.js,如预期.

因为我已经把set tags=./tags,tags;$HOME我的~/.vimrcVim正确地从dir爬到dir直到它到达~/worspace/accordion/tags.即使我在一个不切实际的深层文件树中很深.

Is there an accordion/aa/bb/cc/dd/ee/ff/tags ? no, let's go up…
Is there an accordion/aa/bb/cc/dd/ee/tags ? no, let's go up…
Is there an accordion/aa/bb/cc/dd/tags ? no, let's go up…
Is there an accordion/aa/bb/cc/tags ? no, let's go up…
Is there an accordion/aa/bb/tags ? no, let's go up…
Is there an accordion/aa/tags ? no, let's go up…
Is there an accordion/tags ? yes! let's scan it!

正如另一位评论者反复问你一样没有成功,:pwd你在子目录中的输出是什么？这是另一个要求:输出是:call tagfiles()什么？
